APPARATUS FOR CUTTING CIGARETTE MOUTHPIEQE OR TIP FORMING IVLATERIAL.

Application filed. December 31, 1923.. Serial No. 683,838.

To all whomt' may concern:

Be it known that I, EWALD KOERNER, a citizen of the Republic of Gennany,'a nd resident of Dresden, Germany, have inthe making of tipped or mouthpiece ciga-' gettes, a strip of mouthpiece material is severed into short pieces or strips which are applied to a continuous strip of cigarette wrapper at spaced intervals in advance of the point where the cigarette wrapper receives the tobacco for the formation of the continuous rod. The mouthpiece material r is severed by means of an apparatus which cuts the material into the small strlps, clamps the outstrips and advances the same between feeding and presser rollers between which the cigarette paper is moved. To effect an efficient coordination between the cutting and clamping mechanism and the feeding and presser rollers, it IS highly desirable to produce a compact organization of the parts, and more specifically to so construct and coordinate the operating means that the latter may be brought closely to the rollers, this so that the short tip forming strips are properly advanced and applled to the cigarette wrapper; and a principal object of the present inventlon comprehends the provision of an improved apparatus of this nature.

Further principal objects of the present invention include the provision of a simplified cutting and clamping mechanism wherein the parts are resiliently carried, guided and provided with a fine adjustment; the further provision of an improved cutting device constructed so that the movable or 50 upper cutter may pass the feeding and pressing rollers as closely as possible; and

the still further provision of an improved cutting device in which the upper or movable cutter is adjustable for wear and is made resiliently adjustable with respect a lower cutter.

To the accomplishment-of the foregoing and such other objects asmay hereinafter appear, my invention consists in the elev ments and their relation" one to th'e'other,

as hereinafter particularly described and sought to be defined in the claims, reference being had to the accompanying drawing Fig. 3 is a View similar wag. 1 with the parts shown in another stage of operation displaced one half of a cycle from that shown in Fig. 1,

I which shows a preferred embodiment of my invention, and 111' which:

Fig. 4' is an elevational cross-sectional.

View of the apparatus of Fig. 3, and

Figs. Sand- 6 are front and side elevational views respectively showing improvements in the upper cutting device of the apparatus.

Referring now more in detail to the drawings, the stripcutting and feeding apparatus comprises generally the cutting and clamping mechanism C which operates upon a strip of tipping material t fed therethrough to cut the same into small strips such as t, which latterare advanced for application to the cigarette paper strip 0 which moves between the feeding and presser roll ers a and?) respectively The cutting andclamp-ing mechanism 0 comprises in the preferred embodiment of on the bolt or stud 5 carried by a fixed part of the cigarette machine, the said arm forming aframe providing the'feed table 11 for the mouthpiece Or tipping material and a the invention an arm Soscillatably mounted lower cutter or cutting device 7. Cooper-.

ating with the lower cutter 7 there-is provided the complemental upper cutter 6 mounted on a movable support 14 in almanner described more in detail hereinafter, the cutters 6 and 7 forming in effect a pair of shears extending transversely across for clipping or cutting the tipping material 6 into the mouthpiece strips t; For holding the severed mouthpiece strips, the mechanism.

upon which crank pin 1 is fixed, the said crank pin pivotally carrying the cutting rod 2. To the rod 2 the upper cutter support 14 is attached and the said rod extends below the feeding plane of the table ll and is slidably mounted in suitable guideways in the arm 8. In the operation of this con-' struction upon rotation of the shaft 3 the arm-8 will be oscillated about the shaft or CJI stub 5 and the rod 2 will be given an as cending and descending reciprocatory motion for operating the upper cutter 6 relatively to the, lower cutter for severing the mouthpiece strip zand for effecting a feed ing movement of the table 11 to feed the cut strips t to the rollers a and b.

To effect an eflicient coordination between the cutting and clamping mechanism C and the feeding and presser rollers a and I), it is highly desirable as heretofore stat edto produce a compact organization of the parts, and more specifically to construct and coordinate the operating means for the clamping device so that the latter may be brought closely to said rollers. To accomplish this the clamping device is made L shaped or inverted U shaped, and is made to comprise the preferably profiled transverse clamping arm 10 and one or more operating arms 10* suitably guided below the feeding plane of the table 11 by guideways in the table 11 and in a transverse actuating member 9 connected to the connecting rod 2. The clamping device 10 is normally resiliently urged .into engagement with the cut strips on the table 11 by means of the compression springs 12'surrounding the arms 10?, (0118 end of the springs engaging the table 11 and the other end engaging nuts 13 adjustable on the arms 10 for effecting a fine adjustment of the tension of the clamping device. Upon rotation of the shaft 3 the clamping device 10 will be moved from the descended or clamping position shown in Figs. 1 and 2 to the ascended or releas-v ing position shown in Figs. 3 and 4, the actuating transverse member 9 engaging the nuts 13 and operating the clamping device against the pressure of the springs 12. l/Vith this structure the transverse clamping arm 10 may be desirably brought closely to, the line of contact of the two rollers a and b. I

It is very advantageous as heretofore pointed out, that the cut-off knife or upper cutter pass the feeding and pressing rollers as closely as possible, and to this end'the upper cutting device 6 (see particularly Figs. 2, 5 and 6) is resiliently mounted on the support 1 and in the preferred construction I provide a flat spring 15 secured or attached to the support 14L by means of the screws 19, the saiolflat spring carrying the upper cutter 6' by means'of the screws 17. Preferably to adjust for wear, the up per cutter is adjustably mounted in the spring 15, the latter being to this end provided with the slots 16 adjustably receiving the screwsl'i. For effectinga lateral adjustment of the upper cutter with respect to the lower cutter, I provide the set screws, 18 adjustable in the support 14 and operative upon the flat spring 15 for elfecting'a' resilient lateral adjustment. The elastic mounting of the knife 6 produces a clean out of the mouthpiece or tip forming ma- ,terial, and permits the knife to pass more closely to the feeding and pressing rollers 64 and b. i

The operation of the cutting and clampingapparatus of my invention will in the main be apparent from the above detailed description thereof. It will be further understood that while I have shown my de vice in the preferred form, many modifications andchangesfmay be made in the structure disclosed without departing from the spirit of the invention, lowing claims.
